Here is Live Xiaomi Mi MIX 4 Display

Let me show you the screen of Mi MIX4, the new flexible CUP technology, proactively in the middle of the status bar.  There is almost no difference between the under-screen area and the main screen, and the full-pixel accuracy of 100% completeness is truly full-screen.

The under-screen imaging can also be used normally. It is recommended to squat and watch in pursuit of a full screen.
